This invention relates to cloth brushes and particularly to means whereby a liquid detergent may be delivered to the bristles of Y Jo will flow'through the head of the brush and be delivered to the bristles thereof in such quantities as will prove desirable, the said invention including novel means for controlling the delivery of the cleaning fluid to the brush. It isfurthermore an object of the invention to provide a ibrush. having a reservoir or magazine for containing the cleansing agent and to associate therewith novel 2" means for controlling the How of the deans ing fluid from the container to the brush and the said invention further contemplates the provision of novel means whereby the controlling instrumentality may be shielded or Sliguarded in order that it will not interfere with the manipulation of the brush or prove unsightly;

With the foregoing and other objectsi'n view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter 'more' fully setforth-and claimed.

In describin gthe invention in detail, reference will behad to the accompanying drawings forming part of this application,

wherein like characters denote corresponding parts in the several views, inwhich- Figure 1 illustrates a sectional view of a brush and its attachment, embodying the '40 invention; and

' Figure 2 illustrates a detailview of the controlling device in association with its seat.

In these drawings 5 denotes the head of a brush and 6 the tufts-of bristles which have their ends seated in the head of the brush as is ordinarily done in the manufacture of brushes that are of the wire drawnitype.- a It is intended to supply cleansing fluid, such as gasoline or the like to the. area of the device above the head of the brush and as gasoline is ofa penetrative character it will find its way between the bristles in the head and the said gasoline will enter the tufts of the brush and its presence will invalve screw is preferabl that it may be expedit ously manipulated crease the effectiveness of they bruslf when it is manipulated. If desired, the head of the brushmay be provided with perforations through which gasoline may escape, butit has been found in practice that the arrangement first described will and eflicient. r

The-brush is associated with a reservoir having a shell orcasing 7 which is preferablycurved and internally near the lower edge of the shell or reservoir, a shoulder 8 is formed against which is seated and secured 'a wall or partition 9 which serves to confine the fluid in the reservoir under 'certai'n conditions as will presently beexplained. I

A flange 10 constituting an extension of the shell, in the present embodiment of the invention, .isfprovided, although this construction may be modified to'suit particular requirements and the said flange is ofv a shape to embrace the edge of the head of the brush and the said head is seated'and secured therein by any appropriate packing ll.- There is preferably a space'12 between the inner surface of the brush and the outer surface of the partition or wall 8 and this spaee constitutes a clearancefor the passage of the cleansing agent from the reservoir to theqspace 12. A valveseat is formed in the aperture of the boss and a. tapered valve 15 -coa'cts with the valve seat for closing the passage and the valve will of course be unseated when fluid is to be delivered to the brush.

The aperture '14 is diagonally disposed as shown and the valve is mounted for move-. ment into and out of the seat. In the pres ent embodiment of the invention, the valve is formed asa part of a screw- 16 which is The headI19 of the knurled in order time 18 of the shell prove satisfactory threaded in a bushin 17 secured in an aperand the said valve screw has an a erture 20 through it which acts as a-vent or admit-' ting air to the reservoir when fluid is flowingtherefrom. A gasket 21 of suitable'material is interposed between the head of the valve screw and the brush and any suitable material may be employed for this gasket that will serve to create a leak-proof joint.

The shell has an inturned flange 22 and in producing the flange, the shell is shaped to form a seat in which the head of the valve screw is almost wholly embedded so that it does not project to an extent which will interfere with the manipulation of the brush or the appearance of the device as a whole.

It will be apparent to those skilled in the art that any appropriate joints may be formed between the partition 8 and the shell and that the valve seat may be made of any appropriate material or metal which will withstand wear and insure proper seating of the valve. 4

.The base or partition of the tank should be of a relatively heavy material to prevent bulging when under pressure of'the valve while a layer of solder or other soft metal is used to yield slightly where the valve is seated to make an absolutely tight and gasoline prevention leakage at the bottom, In

other words, if there should be a slight variation in the diameter of the tapered pin 1'5,

this soft metal will yield to the true shape of the pin itself, making an absolutely tight nesting fit. In manufacture, the wood. block of the brush will be vulcanized in the bottom of the shell by hot rubber to prevent any leakage around the edges of the brush,-forcing all gasoline to escape through the bristles, an essential of this improved method of cleaning. Alsothe gasket 27that .fits underneath the head of the plunger to prevent' leakage between the threads will be of rub ber of special compos1tion, resistant to gasoline.

I claim- ,1 V 1. Ina fountain brush, a shell having an aperture the said shell being indented and provided with an inwardly extendin flange around the aperture, a threaded bus ing in the aperture, an externally threaded valve in the bushing, an apertured partition in the shell, said partition having a valve seat at the aperture adapted to coact with the aforesaid valve, a brush head having tufts of bristles through which fluid may penetrate, and means for securing the head of the brush in the shell in ,close proximity to I peripheral portion, said portion being provided with ,a concavity, said concaved portion'having an aperture therein, a threaded bushing in said aperture,.a valve threaded in the bushing'having an air passage therethrough, a wall .in the shell forming a compartment, said wall having an aperture and a valve seat :alining therewith with which the valve coacts, and a brush having a head secured in the shell in positionto head secured in the flange in receive fluid from the reservoir through the aperture in the partition.
